Description

[Detailed Description of the Invention] The present invention relates to a shape forming device for a spring material. Usually, spring materials and the like are formed into various shapes depending on the purpose of use.

For example, even in commonly used leaf springs, the spring is used with a curvature. Conventionally, the shape of a leaf spring has been formed by the method shown in FIG.

That is, as shown in the figure, a leaf spring 1 is fed by a motor 4 between rollers 2 and 3, and the fed leaf spring 1 is bent onto a support bar 5 placed at a position that matches the shape. A leaf spring was processed into the shape of .

However, with this method, it is possible to give a sufficient shape to a relatively thick plate, but it is difficult to form a thin plate spring etc. into a predetermined shape due to the strong return force. It was hot.

Although this method is possible for thick and large leaf springs, it is difficult to apply it to small leaf springs.

SUMMARY OF THE INVENTION An object of the present invention is to provide a shape forming apparatus for a spring material that can accurately bend a thin and small leaf spring in order to eliminate the above-mentioned conventional drawbacks.

Therefore, in the present invention, the workpiece is placed on a flat elastic member provided on the base, and
A roll is provided opposite to this elastic member, and the spring material is pressed by this roll, and the roll is rolled in this state.

That is, the present invention is a shape forming device for a spring material that can easily form a thin leaf spring into a predetermined shape, and can also form a small leaf spring into a predetermined shape. , the spring material to be processed in a predetermined manner is sunk in an elastic member by a roll, and the roll is rolled on the spring material.

The present invention will be explained in detail below with reference to the drawings.

FIG. 2 shows an embodiment of the spring material shape forming apparatus of the present invention.

In the figure, the same symbols as in FIG.
13 represents a motor, 13 represents an elastic member, and 14 represents a base body.

The spring material shape forming device of the present invention includes an elastic member 1
Place the leaf spring 1 on top of the spring 3.

In the embodiment, a recess as shown in the figure is provided on the base 14, and the elastic member 13 is provided in this recess.

This elastic member 13 can be made of rubber, resin, or the like. A spring material 1 for forming a desired shape at a desired position on the elastic member 13 is arranged as shown in the figure. A roll 6 is arranged on the spring material 1 and supported by guides 7 and 8.

These guides 7 and 8 include screw rods 9 and 8.
10, and motors 11 and 12 cause the roll 6 to roll on the spring material 1.

Now, if this spring material 1 is to be given a predetermined shape, the roll 6 is pressed down onto the elastic member 13 to sink the spring material 1 into the elastic member 13. The amount of sinking of the spring material 1 with respect to the elastic member 13 is proportional to the angle O applied to the spring material, and this relationship may be measured in advance.

Furthermore, since the radius of curvature R of the spring material 1 is determined by the diameter of the roll 6, a desired radius R can be determined by replacing the roll 6.

Furthermore, by changing the shape of the roll 6 in various ways, not only the radius of curvature R but also a right angle bend is possible.

Although the amount by which the spring material 1 sinks relative to the elastic member 13 is not shown, it is sufficient to press down the roll 6 by a predetermined amount.

It is also possible to form a U-shape on the spring material 1 by rolling it over the spring material 1 using the motors 11 and 12.

As described above, the spring material shape forming apparatus of the present invention can easily form a thin plate into a desired shape, and has the effect of being suitable for forming the shape of a small spring material.
